Abstract
Raw sausage meat lumps are mixed and comminuted in a bowl by a rotary cutter driven by an AC drive motor. The motor speed is controlled as a function of frequency and the number of poles for the motor.
Claims5
An energy-efficient, raw sausage meat processing apparatus, comprising:
- (a) a bowl for containing raw sausage meat lumps to be processed;
- (b) means for mixing and comminuting the meat lumps, including a rotary cutter rotatably driven in the bowl;
- (c) a frequency-controlled, variable speed, AC drive motor having a plurality of poles and energized by an electrical power source, said motor having an output shaft on which the cutter is mounted for rotation at low speeds for mixing and coarsely cutting the meat lumps, and at high speeds for mixing and finely cutting the meat lumps;
- and
- (d) control means for controlling the motor speed as a function of frequency and the number of poles for the motor, including a frequency converter operatively connected between the power source and the motor, and means for adjusting the frequency of the converter for changing the motor speed to a desired energy-efficient magnitude appropriate for processing the meat lumps without spoiling their inherent flavor.
